title: F-18 FDG PET/CT imaging of solitary genital tuberculosis mimicking recurrent lymphoma.
abstract: A 65-year-old man who had multiple lymph nodes swelling was pathologically diagnosed with diffuse large B cell lymphoma. After initiation of induction chemotherapy, F-18 FDG PET/CT showed a significantly decreased extent of previous lymphomatous lesions except for 2 newly developed focal hypermetabolic lesions in the prostate and left epididymis. The specimens from the prostate and orchiectomy revealed tuberculosis lesions. After a 3-month antituberculosis regimen, there was definitively decreased glucose uptake in the prostate on F-18 FDG PET. F-18 FDG PET may be helpful for characterizing genitourinary tuberculosis and monitoring antituberculosis treatment.
